Unlocking the QPE Mystery: Star-Disk Collisions in Realistic AGN Disks
Zhaohuan Zhu, Xiaoshan Huang, Yan-Fei Jiang +1
Quasi-periodic eruptions (QPEs) are luminous, recurring soft X-ray outbursts observed in the nuclei of low-mass galaxies. They display two remarkable trends: outburst durations are…
2D hydrodynamical simulations of Be star decretion disc formation through boundary layer effects
Madeline Overton, Zhaohuan Zhu, Rebecca G. Martin +1
Be stars are massive main-sequence stars rotating close to their breakup rate. They possess a decretion disc of material built up due to mass loss from the star, however, there is…
Resolving Oblique Star-Disk Collisions in Quasi-Periodic Eruptions: Numerical Requirements and the Importance of Geometry
Shunquan Huang, Xiaoshan Huang, Zhaohuan Zhu +1
Star-disk collisions have been proposed as a promising mechanism for producing quasi-periodic eruptions (QPEs) in galactic nuclei. Because the stellar atmospheric scale height is o…
Primordial planet spin driven by boundary layer effects in a decretion disc
Rebecca G. Martin, Stephen H. Lubow, David Vallet +4
Accretion of material from a protoplanetary disc on to a forming giant planet can spin the planet up to close to its breakup rate, , where $M_{…
Formation of Be star decretion discs through boundary layer effects
Rebecca G. Martin, Stephen H. Lubow, David Vallet +3
Be stars are rapidly rotating, with angular frequency around of their Keplerian break up frequency, as a result of significant accretion during the earlier stellar evolut…
Global 3-D Simulations of Magnetospheric Accretion: II. Hot Spots, Equilibrium Torque, Episodic Wind, and Midplane Outflow
Zhaohuan Zhu
Global 3-D magnetohydrodynamical simulations have been conducted to study magnetospheric accretion around stars with various spin rates. For slow rotators, characterized by a fastn…
The effects of the carbon-to-oxygen ratio on the condensate compositions around Solar-like stars
Cody J. Shakespeare, Min Li, Shichun Huang +2
The initial stellar carbon-to-oxygen (C/O) ratio can have a large impact on the resulting condensed species present in the protoplanetary disk and, hence, the composition of the bo…
Relativistic Effects on Circumbinary Disk Evolution: Breaking the Polar Alignment around Eccentric Black Hole Binary Systems
Anna C. Childs, Rebecca G. Martin, C. J. Nixon +4
We study the effects of general relativity (GR) on the evolution and alignment of circumbinary disks around binaries on all scales. We implement relativistic apsidal precession of…
Growing Planet Envelopes in Spite of Recycling Flows
Avery Bailey, Zhaohuan Zhu
The hydrodynamic exchange of a protoplanet's envelope material with the background protoplanetary disk has been proposed as one mechanism to account for the diversity of observed p…
Warps and Breaks in Circumbinary Discs
Ian Rabago, Zhaohuan Zhu, Stephen Lubow +1
Disc warping, and possibly disc breaking, has been observed in protoplanetary discs around both single and multiple stars. Large warps can break the disc, producing multiple observ…
A Tale of Two Grains: impact of grain size on ring formation via nonideal MHD processes
Xiao Hu, Lile Wang, Satoshi Okuzumi +1
Substructures in PPDs, whose ubiquity was unveiled by recent ALMA observations, are widely discussed regarding their possible origins. We carry out global full magnetohydrodynamic…
Non-ideal MHD simulation of HL Tau disk: formation of rings
Xiao Hu, Zhaohuan Zhu, Satoshi Okuzumi +4
Recent high resolution observations unveil ring structures in circumstellar disks. The origin of these rings has been widely investigated under various theoretical scenarios. In th…
